Description
TMAH Developer is a commonly used developer, and its main component is
tetramethylammonium hydroxide. TMAH is an organic base with strong alkalinity,
which can cause the developer to deposit on the silver salt grains to form a
black silver image. On the other hand, it has its unique characteristics, that
is, it will not leave metal ions during use, and can be decomposed into
trimethylamine gas and methanol gas without leaving any traces after heating,
and can be widely used in the modern electronics industry. In addition to TMAH,
our company will also add some independently developed additives to adjust the
speed and effect of the developer. In order to avoid the collapse of the
photoresist lines, a small amount of surfactant can also be added to the TMAH
aqueous solution.

TMAH Developer (Tetramethylammonium Hydroxide) is a critical solution in the
semiconductor manufacturing process, specifically for photolithography
applications. It offers precise and consistent development of positive
photoresists, enabling high-resolution patterning required in advanced
microelectronics. Our TMAH Developer is designed to meet the rigorous demands
of the industry, with customizable options to support diverse manufacturing and
R&D needs.

TMAH has strong alkalinity
Tetramethylammonium hydroxide (TMAH) is a strong alkalinity organic base with a
molecular formula of (CH3)4NOH. Its strong alkalinity is mainly reflected in
its pH value greater than 13. It can quickly absorb carbon dioxide in the air
to form carbonates, and its alkalinity is stronger than common inorganic bases
such as sodium hydroxide (NaOH) and potassium hydroxide (KOH). The strong
alkalinity of TMAH comes from the quaternary ammonium cations (CH3)4N+ and
hydroxide ions OH− in its molecular structure. This structure makes it
completely ionized in water and exhibits strong alkalinity.
